Wordize for .NET is a professional solution for automated reporting and programmatic ODT document generation. The ReportBuilder class provides C# developers with the capability to create ODT reports using templates and LINQ syntax, which helps accelerate business intelligence processes, implement dynamic ODT content in automated document workflows.

Key Features:

Programmatic ODT report generation - the ReportBuilder class provides the BuildReport() method for creating ODT documents based on templates
Flexible data source integration - support for JSON, XML, CSV and programmatic objects (custom classes, object collections)
LINQ expressions application for filtering, sorting and grouping data when generating ODT
ODT generation parameter configuration - the ReportBuilderOptions class manages available data types, missing field handling, empty paragraph removal and other report creation parameters in ODT format
Export to graphics format - the BuildReportToImages() method returns ODT report pages as an array of images
Fluent API support for launching report creation operations through ReportBuilderContext and method chaining, adding clarity to C# code

Test the capabilities of programmatic ODT report generation in the interactive online demo presented on this page. To do this, upload a document template, data file (JSON, XML or CSV), run the operation and download the generated ODT document for verification. The provided C# code snippet is fully ready for use in your .NET project.
